Is there an algorithm to decompress the IIMU data that allows continuous collection of the FIFO data when timestamp, accelerometer and gyroscope buffering is enabled in FIFO? The App note gives some ideas how to decompress but not the algorithm - loo...

LSM3DSO IMU: How many words with high compression (3xC) [each XL or GY] can be sent in a row by IMU? I suspect not more than twice in a row. For example:...-GY 3xC-Timestamp-GY 3xCor ...-XL 3xCTimestamp-XL 3xCIn other words, this case is not possible...

Any ideas on why the timestamp gets reset in FIFO after 0xFFFF? I have TIMESTAMP_EN bit of theCTRL10_C register set to 1 and the DEC_TS_BATCH_[1:0] bits of the FIFO_CTRL4 are set to 01 (max(BDR_XL[Hz],BDR_GY[Hz]) [Hz]).

LSM6DSO Application Note, page 67: The value is expressed as a 16-bit word in two’s complement.Question: is this a SIGNED or UNSIGNED value?

Why did you guys remove the feature of resetting the timer for LSM6DSO IMU? It was available in LSM6DS3 by setting AAh in TIMESTAMP2_REG (42h).How do we reset the timestamp value in FIFO (LSM6DSO chip)?

Sorry you have not answered my question.

They store data in separate arrays, acc_data[] and gyr_data[] each of them includes a timestamp. What is the way to store data in one array which includes a timestamp, accelerometer X,Y,Z and gyroscope X,Y,Z data? I need to store samples matching the...

Thanks Eleon!

Yes, for the FIFO data the spec explicitly states the data is signed since they are encoded with two's complement; but for the OUTX_L_A (28h) and OUTX_H_A (29h) for example are not explicitly state that they are signed two's complement values. see p....

Eleon,This is weird that the SIGNED is not mentioned in the datasheet or the Application note, where it is specifically says for 5bit_signed and 8bit_signed values for the compressed data. In your examples, why the MSB value is not considered for con...
